of Molding-lllachines, of which the followmg is a specification.

ll ly invention relates to an automatic machine for inserting andremoving core poles from the molds of continuously operable moldingmachines and particularly the plaster block molding machines describedin the application of Charles R. Birdsey and (harles F. Henning, PatentNo. 1,116,669, November 10, 191%. In molding machines of this charactera plurality of core poles are inserted in each mold and supported onsuitable openings in the sides thereof in order that the block may bepartially hollow and therefore lighter in Weight than a solid bloclc.Heretofore it has been customary to employ men to insert the core polesprevious to filling the molds with plastic material and to remove thembefore the blocks are delivered from the machine. In molding machines ofconsiderable size and large output a number of men are requiredconstantly to perform the necessary operations, thus entailing aconsiderable additional expense.

It is an object of my invention to provide a machine which willautomatically insert and remove the core poles from the molds at properintervals without manual assistance of any kind. I

Other objects and advantages of my invention will be apparent as it isbetter understood by reference to the accompanying specification inconnection'with the accompanying drawings in which t 'Figure 1 is a planview of my invention with a portion of a block molding machine showingthe operation of removing the core poles from the molds; Fig. 2 is aside elevation of my present invention; Fig. 3 is a transverse sectionthrough my present invention and the molding machine, a portion Fig. 4is of a portion of a single core and a portion of the correpo'n'd'ingmold with the core poles in place; Fig. 5 is a vcrticalasection on theline 55 a plan view Specification of Letters Patent.

eferring to the drawings, generally a molding machine of the typedescribed in the application to Birdsey and 1 indicates view of thelower a Henning, previously referred to, which comprises a plurality ofmolds 2 endless band adapted to be continuously moved in the directionindicated by the arrow in Fig. 1. Each of the molds is provided withends 3 (see Fig. 5) having a plurality of openings to accommodate thecore poles 4, which are inserted in the molds previous to filling thesame and removed therefrom after the material has hardened. The objectof the core poles 4, as has previously been explained, is to provideopenings through the blocks, formed in the molds, in order that they maybe lighter in weight than solid blocks. For this purpose I prefer toemploy a tapered hollow metal p0 e.

My present invention forming comprises an end less com'eyer adapted tobe disposed adjaas indicated in means for automati- 5 are shafts 8 and9, respectively, which sup port the sprockets 10. The brackets 7- areprovided with adjusting means 11, whereby the shaft 9 may be movedto andfrom the frame 5 to provide proper tension in the endless conveyer. Theshaft 8 is adapted to be driven through a sprocket 12, mounted block hashardthereon, and a chain 13, from any suitable source of power,preferably the driving means for the molding machine. The endlessconveyer consists of a plurality of articulated members 14, eachcomprising a bottom plate 16 having depending portions 17 formingjournals for the axles 18 to which the wheels 15 are secured. The wheels15 run on tracks 16 and 16". secured to the frame 5. The bottom plates16 are further provided with grooves or runways 19 in which the corepole carriers 20 are adapted to be reciprocated as will presently be explained. The core pole carriers 20 are held in the grooves 19 by plates19 bolted to the bottom plates 16. At either end the endless conveyor isdisposed about the sprockets 10, whereby the conveyer is driven in thedirec- :tion indicated by the arrows in Figs. 1 and 2.

The c ore'polq carriers 20 comprise a base port-ion 21 adapted to beslid-ably mounted in the grooves 19 and an upstanding portion 22 towhich a plurality of pins 23 are secured by bolts or other suitablemeans 24. The pins 23 are preferably of skeleton form, as indicated inFigs. 6 and 7, to reduce the weight thereof and are adapted to enter thecore poles 4 during the operation of the machine and support them asthey are withdrawn and until they are re-inserted in the molds 2. Theupstanding portion 22 of each core pole carrier 20 is provided withextensions 24' at either end thereof to support the clamp 25 which isadapted to engage the core poles 4 between the flanges 26 thereon andhold them rigidly on the pins 23, while the core poles are withdrawnfrom and until they are again inserted into the molds 2. The clamp 25 isslidably mounted at either 1-0 end on pins 27 between" abntments 29 and29 and is normally forced into clamping position by springs 28 disposedabout the pins 27 between the abutments 29 and the clamp 25. The clamp25 is provided near its center i with a bent pin 30 suitably securedthereto,

which pin is adapted ti ride upon a cam plate 31 (see Fig. 3), seemed toa transverse member 32 of the frame 5, as the individual conveyer member14 approaches the core V pole removing position, to lift the clamp 25 tothe position indicated in Fig. 9 so that it can pass over the flanges 26of the core poles 4. \Vhen the core pole carrying member 20 has beenforced to its foremost position, through mechanism which will pres- 60ported and held on the pins 23.

cntly be described, the pin 30 drops from the cam plate 31 and thesprings 28 force tliev clamp 25 to the,position shown in Fig. 8, wherebythe core poles 4 are rigidly sup- The core poles 4 are then withdrawnfrom the molds by the rearward movement of the core pole carrier 20. 1

The movements of the core pole carrier 20 from and toward the moldingmachine to withdraw and insert the core poles 4-in the molds 2 arecontrolled by means of cam tracks 33, 34 (see Fig. 1), 35 and 36 (seeFig. 10), mounted on the transverse members 32 and 33 of the frame 5above and below the conveyer, respectively. Each of the core polecarriers 20 is provided with an upstanding member 36' carrying a pivot37 upon which is disposed a-roller 38 adapted to coact with the camtracl'". 33, 34, 35 and 36. As the conveyer moves 1n the directionindicated by the arrow in Fig. 1 the core pole carriers 20 approach thecam track 33 until an individual roller 38 contacts therewith whereuponthe core pole carrier 20 corresponding to the roller 38 is forcedforwardly, while at the same time the clamp 25 is gradually raisedthrough the medium of cam plate 31. Simultaneously the pins 23 willenter the hollow core pole 4 and when, as has been previously explained,the core pole carrier 20 reaches its foremost position with the face ofthe upstanding portion 22 disposed adjacent the end of the core poles 4of one of the molds 2 the bent pin 30 is released from the cam plate 31and the clamp 25 will be forced into engagement with the core-pole 4 tofirmly clamp them upon the pins 23. The continued movement of thcconveyer in the direction of the arrow will carry the roller 38 into thecam track 34 and the core pole carrier 20 will be forced rearwardly,gradually withdrawing the core poles 4 from the molds 2. \Vhen the corepo es 4 have been entirely withdrawn the molded blocks are free so thatthey may be removed from the molds at the discharge point. The movementof the conveyor carries the core poles 4 to the under side of themachine where the individual rollers 38 engage the cam track 35 (seeFig. 10) whole upon the core pole carrier 20 corresponding thereto ismoved forwardly to re-inscrt the core poles 4 in the empty molds 2 onthe under side of the molding machine. It is, of course, to beunderstood that the core pole carriers 20 are moved in synchronism withthe molds 2 of the molding machine and that while the molding machine ismany times longer than my core pole removing and inserting device a mold2 will alwavs be forced the clamp 25 downwardly to free the core poles 4from the carrier 20. The roller 38 will then pass into the cam track 36(see Fig. 10) whereby the core pole carrier is moved rearwardlywithdrawing the wins 23 from the core poles 4 and leaving t as core beof pins and with etro poles adjusted in the molds 2. The molds 2,carrying the core poles, may then proceed to the filling position whilethe core pole carriers move to the upper-side of the Inaand clamps tosupport four core poles for each mold. It is obvious, however, that, as

1Q frequently desirable, a greater or less number of core poles may beused in the molds and consequently the core pole carriers may besupplied with a corresponding numclamps adapted to coact with such pins.L therefore, construct the core pole carrier 23 may be inserted invarious positions and also provide interchangeable clamps 25 adapted tocoact with the. pins v 23 in their various positions.

there is considerable adhesion between the material from which theblocks are molded and the core poles 4 l have found it desirable tomount a plurality of rollers 40 on the frame adjacent the position atwhich the core poles dare picked up by the core pole carriers 20, suchrollers being arranged engage the ends of the core poles 41 before theyare gripped by the clamps 25 and gradually force the core polesrearwardly from their that the heads thereof bearing the flanges 26 arein proper position to, be gripped by the clamps when the clamps arereleased from the cam plate 31. The actionof the rollers 16 trees thecore poles 4 and prevents unnecessary strain upon the core pole carriers20 as they are moved rearwardly by the cam track 34: to remove the corepoles from the molds. p

is thought that my invention will be readily understood from theforegoing description without further explanation. It will be apparentthat l. have succeeded in perfecting a machine whereby the arduous laborconnected with the insertion and removal of core poles from continuouslyoperable molding machines is entirely eliminated and that by the use ofmy machine the necessity of providlng a number attend the machinedispensed with. the
